“…Microfacies type and its relationship to sea-level fluctuation have been documented previously by many workers (Han, Hu, Li, & Garzanti, 2016;Touir, Haj, & Quali, 2018). Microscopic investigation reveals that the alternation of various microfacies are generally recognized in the lower part of the studied sections (Zarghan, Kuh-e Siah, Kuh-e Khanehkat and Kuh-e Chehelcheshmeh) (Figure 8a-c), whereas the mentioned identified microfacies variation is distinguishable only in the upper part of Kherameh-1 and Kherameh-2 sections (Figure 9a,b).…”

Over 3,000 m of Upper Cretaceous‐Lower Palaeocene sediments belonging to the Tarbur Formation were studied in seven stratigraphic sections around Shiraz city (south Zagros Basin, SW of Iran). The Tarbur Formation is divided into two informal lithostratigraphic units: a lower well‐bedded rudist limestone and an upper massive rudist limestone. Both units comprise rudist particles as a major organo‐detrital component. Microscopic studies have identified the presence of the following carbonate microfacies types in the Tarbur Formation: rudist orbitoid wackestone, miliolid algal‐bioclast wackestone, rudist packstone, rudist orbitoid packstone, rudist intraclast miliolid packstone, rudist‐agglutinated foraminifer grainstone, orbitoid rudist grainstone, rudist‐hyaline foraminifer‐intraclast grainstone, rudist boundstone and coral boundstone, which are attributed to shallow water lagoon, bar and fore‐reef palaeoenvironments. The rudist fragments co‐existed with a Campanian/Maastrichtian foraminiferal assemblage. The stratigraphic distribution of the investigated microfacies was affected by vertical displacement of studied area basement faults.

“…Eustasy, subsidence, sediment supply, climate, and paleoceanography are considered major factors in sea-level changes (Emery and Myers, 1996;Pomar and Kendall, 2008;Catuneanu et al, 2011). The interaction between eustatic sea-level changes and local tectonics plays a vital role in shaping different types of platforms by determining key sedimentary attributes (Dorsey and Umhoefer, 2000;Haq and Al-Qahtani, 2005;Touir et al, 2018;Luan et al, 2023). Platform evolution in the spatial and temporal framework in active basins has been inferred via the study of depositional and structural characteristics, which in turn affect carbonate production and detrital input (Rosales, 1999;Steuber, 2002;Wu et al, 2016).…”

The Qom Formation is the most important hydrocarbon reservoir target in Central Iran. The Qom platform developed in a back‐arc basin during the Oligo‐Miocene due to the closing of the Tethyan Seaway. This formation consists of a variety of carbonate and non‐carbonate facies deposited on a platform ranging from supratidal to basin. A combination of tectonic and eustatic events led to some lateral and vertical facies variations in the study area. Six third‐order depositional sequences and related surfaces were identified regarding vertical facies changes in the studied sections of this Oligo‐Miocene succession. According to all results and data, this succession was initially deposited during the Chattian upon a distally steepened ramp of siliciclastic‐carbonate composition, including the Bouma sequence. Then, from the late Chattian to the Aquitanian, the platform changed into a homoclinal carbonate ramp with a gentle profile. With respect to tectonic activity, this phase was a calm period during the deposition of the Qom Formation. Finally, a drowned carbonate platform and a rimmed shelf emerged during the Burdigalian, terminated by the continental deposits of the Upper Red Formation. Regarding all geological characteristics, three main tectono‐eustatic evolutionary phases have been recognized in the Qom back‐arc Basin.
